After releasing the sharks back into the water, they can track the shark with underwater buoys that records information when a shark nears the vicinity.
In addition the group also uses spearguns to “shoot” a tag into the dorsal fins of adult bull sharks.
The goal is to protect the bull sharks mating and berthing areas.
Once the data is collected the team hopes to find out if the sharks are traveling outside of the Protected Marine area and if so they hope to present the information so that the area can be expanded.
